| titleOfInvention | A kind of high-strength size-free polylactic acid yarn and preparation method thereof |
| abstract | The invention discloses a high-strength size-free polylactic acid PLA yarn and a preparation method thereof. The high-strength size-free PLA yarn is composed of PLA short fibers with a linear density of 1.3-7.7 dtex and a length of 25-150 mm. Core structure, the skin layer is low melting point PLA, the core layer is high melting point PLA, the mass ratio of the skin layer and the core layer is 5:90～50:50; the preparation method of the high-strength pulp-free PLA yarn is: the raw materials of the skin layer and the core layer are baked After drying, they are added to the corresponding hoppers of the composite spinning machine, and are transported through the melt—spinning—air cooling—winding and feeding—oil bath drawing—steam bath drawing—tensile heat setting— - Oiling - piling - crimping - relaxing - cutting process to obtain PLA short fibers with sheath-core structure; using sheath-core structure PLA short fibers as raw materials, spinning to obtain PLA yarns, and then PLA yarns Through a pair of heating rollers, PLA is heated and pressurized to obtain high-strength sizing-free yarn. The heating temperature is higher than the melting point of the skin layer PLA and lower than the melting point of the core layer PLA. The cohesion force of the yarn is high, and the high strength and size-free of the yarn are realized. The obtained high-strength size-free PLA yarn can be used in the fields of apparel textiles, decorative textiles and technical textiles. |
